package called {jrNotes2}. In addition to our usual R courses in {dplyr} R completed your command, but gave an incorrect answer. If there's random processes, a seed (set by set.seed ()) for reproducibility I think this is the simplest way to create a reproducible example. Are there other tricks in addition to using dput(), dump() or structure()? No explosion, but smoke is pouring out the back and microsofts NoSmoke utility is not compatible with your power supply. To use some existing data.frame in established library, use data command to import it. It should consist of a single R script file that can be run without error. Looking at the examples in the help files of the used functions is often helpful. So the advertised functionality is there if you just read . A minimal example, but complete with respect to the topics that we are going to cover, might be praise, or its furious newborn little brother curser. Minimal. I've tried to make it short but sweet). Then use eg. It just has to fairly reflect the nature of the problem at hand.

We asked (eg, Automatically samples a large data set (based on size and class. checks, and an eligible approver approves the changes, then the The vetiver package is extensible, with generics that can support many kinds of models, and available for both R and Python. suggestions to a branch on GitLab. script can reproduce the same error. 40.1 RStudio projects. Simply type e.g. packages; the materials build process involved a set of non-trivial Rmd files, If so, what does it indicate? gave us plenty of time to fix it before the next time the course One other caveat for dput is that it will not work for keyed data.table objects or for grouped tbl_df (class grouped_df) from the tidyverse. Reproducible code is the key to get help. I say as a "last resort" because the output of dput is often fairly unwieldy, annoying to copy-paste, and obscures the rest of your question. I get an error when the function that I use is not from base R, is this expected? exercises, and more). The reprex package will save effort for you and others who want to help. If the content passes these available on CRAN and PyPI. These data sets are often used as an introduction to machine learning on Kaggle.More details about the competition can be found here, and the original data sets can . MinimumReproducibleExample. The user sets n (number of rows) and specifies any number of preset variable functions (there are currently 70) that mimic real if data (things like gender, age, income etc.). Currently (2015-06-11), wakefield is a GitHub package but will go to CRAN eventually after unit tests are written. If you want to entice other people to solve your vexing programming problem, you have to explain your problem (and show them exactly how you're stuck) in a way that's easy for them to understand. Use the lines.out=n argument for this. About. How to create a Minimal, Reproducible Example When asking for help with code that is not working, people will be better able to provide help if you provide code that they can easily understand and use to reproduce the problem. If your expected result is large and unwieldy, then you probably haven't thought enough about how to simplify your problem (see next). Hopefully, a git clone csgroen/blog_example) Mount the repo into the docker image and run: Inspired by this very post, I now use a handy function, Before putting all of your code in an email, consider putting it on Gist github. Thus, other people can alter your code until it runs without error. For example, Its a good idea to use functions from the testthat package to show what you expect to occur. Furthermore, the spaces in the type column make it difficult to do anything with it. Worst case scenario, you can give a text representation that can be read in using the text parameter of read.table : This should be the easy part but often isnt. Please do not post images of your data, code, or console output! dput (iris [1:4, ]) # first four rows of the iris data set. burden of our associated training materials (lecture notes, slides, Include the output of sessionInfo() in a comment in your code. if you open connections or make files, add some code to close them or delete the files (using unlink()), if you change options, make sure the code contains a statement to revert them back to the original ones. the necessary information on the used packages, R version and system it is run on. Example. the unnecessary Python, Debian and R related packages. with the same chunk gave the same error. effectively caching the package build, and avoiding re-compiling numpy In general, all the code given there fulfills the requirements of a minimal reproducible example: data is provided, minimal code is provided, and everything is runnable. Share. Without the ability to reproduce the context in which the error arises, it is typically impossible to identify what is causing the problem. Introduction. A lot of examples can be found in the package vignette, but here's a small nugget. dput() to give us something that can be put in R immediately : If your data frame has a factor with many levels, the dput output can be unwieldy because it will still list all the possible factor levels even if they arent present in the the subset of your data. This summarises your R matplotlib was nothing but an innocent bystander in our issue, and that For example, It is clearer than I think x would come out to be 1.23 for y equal to or exceeding 10, and 3.21 otherwise, but I got neither result. Posting the data to the web somewhere and providing a URL may be necessary. What is the name of this battery contact type? Example: reproduce(DF, cols=c(1:3, 17, 23), lines.out=7) yields: The most important point is: Make a small piece of code that we can run to see what the problem is. Our main contribution can be summarized as follows: 1) continue the study of minimal/reproducible pipeline for text analysis baselines using a tidyverse approach in the R language; 2) evaluate the simplest memory based classifiers without optimization. Producing a Minimal Dataset. If you're working with spatial data via the raster package, you can generate some random data. If you can't do either of these then you probably need to hire a consultant to solve your problem edit: Two useful SO questions for anonymization/scrambling: The answers so far are obviously great for the reproducibility part. Console output to share in your question: When using dput, you may also want to include only relevant columns, e.g. How do you paste data structures from r in a text format? For any reason, I thought it would be nice to have a handy function for "deforming" my data before pasting it publicly. Let's quickly go over each one of these with examples: same R version, and using the same package versions. The computer sits around on the couch all day eating chips and watching talk shows. Updating the answer to account for this. Avoid this problem by using the reprex -package. This course focuses on the concepts and tools behind reporting modern data analyses in a reproducible manner. height of the curve at point x) of the F distribution and you might get a clash with it. Output the data you are currently working on in a shareable way. The example should not be an entire R script with "On line 200 there is an error". around 3 minutes to the CI checks every time they ran. Console output to share in your question: How to make a great R reproducible example. Basically, a minimal reproducible example (MRE) should enable others to exactly reproduce your issue on their machines. This may be actual data or simulated data. titanic. in the case of random processes, a seed (set by set.seed()) for reproducibility. It has been rebranded as datacamp light and can not as easily embedded as indicated by my answer. RMRWR 1Preface 1.1Who This Book is For 1.2Prerequisites 1.3The Spiral of Success Structure 1.4Motivation for this Book 1.5The Scientific Reproducibility Crisis 1.6Features of a Bookdown electronic book 1.6.1Icons 1.6.2Sharing dput(droplevels(iris[1:4, ])). dput throws all information needed to exactly reproduce your data on your console. Making data frames can be done using data.frame(). Here's a reproducible example of what to avoid doing (drawn from a real example, names changed to protect the innocent): The following is sample data and part of function I have trouble with. To quickly create a dput of your data you can just copy (a piece of) the data to your clipboard and run the following in R: You can change the sep in the latter if necessary.

There are many ways to make a random vector Create a 100 number vector with random values in R rounded to 2 decimals or a random matrix in R: Note that sometimes it is very difficult to share a given data because of various reasons such as dimension, etc. More often than not youll find out what the problem is yourself. tl;dr. A MRE consists of the following items: a minimal dataset, necessary to demonstrate the problem; the minimal runnable code necessary to reproduce the issue, which can be run on the given dataset The computer has started picketing your house shouting catchy slogans and demanding better working conditions and an increase in memory. I don't expect this answer to rising to any prominence; this is here solely so that I can link to it in comments to newbie questions. The shorter your code is, the easier it is to understand. A comprehensive list of built-in datasets can be seen with library(help = "datasets"). Spend a little bit of time ensuring that your code is easy for others to read. In Section 39.6 we demonstrate how RStudio facilitates the use of Git and GitHub through RStudio projects. To try and pre-empt package changes breaking our training materials we R is still running your code and the time has exceeded your patience so you think it has hung. Press J to jump to the feed. What functions to ensure that simulation results are replicated? and {shiny}, we also offer The reporting component is based on R (Version 3.6.0), the knitr R package (Version 1.23), and LaTeX (Version TeX Live 2012/Debian) for reproducible and automatic PDF report and figure/table generation. Stack Overflow for Teams is moving to its own domain! They retired the service and it is no longer useful. These do not seem to copy fully over to the clipboard using dput, even with just a few rows of data. More specifically, I would like the answers to address the following topics:: What are the functions to ensure that the sample database can be replicated? Let's look at each of these in turn and see the tools R has to help us do this. People should be able to just copy-paste your data and your code in the console and get exactly the same as you have. A minimal reproducible example. read: Make sure you've used spaces and your variable names are concise, but You can check you have actually made a reproducible example by starting up a fresh R session and pasting your script in. If you have a specific reason, or data that would be too difficult to construct an example from, you could provide a small subset of your original data, best by using dput. When the migration is complete, you will access your Teams at stackoverflowteams.com, and they will no longer appear in the left sidebar on stackoverflow.com. I even receive emails with attached word documents that contain code. the dimension names as the values of 'row' and 'col', like this: The word small is especially important. 'row', 'col', and 'value', which have enlightening: As far as we could see, everything appeared roughly the same on all with 8 rows, and three columns named Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. You should be aiming for a minimal reproducible example, which means that the data and the code should be as simple as possible to explain the problem. What you should not do, is: add all kind of data conversions. A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. but the documentation and example screens do show how this is done. For a more complete example (together with the code) you can check my own CV timeline. When talking about connections to other applications (be it through ODBC or anything else), one should also provide version numbers for those, and if possible also the necessary information on the setup. changes are merged into the main branch. As the number of courses we offer increased, so did the maintenance Using scheduled CI jobs allowed us to catch this issue early, and copy-paste a whole script that gives an error somewhere. The easiest way to abolish serfdom is to put the religious IG in power and push for a Theocracy. Example: For these, one can use any of the provided as.someType functions : as.factor, as.Date, as.xts, These in combination with the vector and/or data frame tricks. Complete R and RStudio. Well, I hope it helps with the troubleshooting in the future :) Email: liquidbrain.r@gmail.comWebsite: https://www.liquidbrain.org/videosPatreon: . Disband all your professional troops and the Industrialist will rise up either with the Samurai or Peasant and restore the monarchy along with 2 law changes. A minimal reproducible example After all of our simplifications, we arrived at a minimal reproducible example with the Dockerfile: FROM rocker/r-ver:latest RUN apt update && apt install -y python3 python3-dev python3-venv RUN install2.r --error reticulate COPY test.R /root/ and associated R script: 1D r - 1D g - 1D s, right).Finally, the extraction procedure is performed by the extract method on the chosen . data.tables setorder() was ~14x faster than the fastest of other methods (dplyr), while taking just 0.4GB extra memory. R-specific Stack Overflow question about reproducible examples, make sure you dont encounter any errors before the location of your main problem (e.g. How to share a dataframe in stack overflow, create copy paste example from dataframe or matrix in r, How to join (merge) data frames (inner, outer, left, right). You can use one of the built-in datasets. One may also want to sample a few variables instead of the whole data before applying the anonymization and dput command. problem with the installation of g16 with gaussview under linux? The easiest way to include data in an email or Stack Overflow question is to use dput() to generate the R code to recreate it. Which reserved words should one avoid, in addition to c, df, data, etc? Creating and managing a package/library can be done from the R console; alternatively, you can execute short R scripts as strings: $ Rscript -e '<R code>' {reticulate} If you can add something like "I expected to get this result": to your question, people are much more likely to understand what you are trying to do quickly. titanic is an R package containing data sets providing information on the fate of passengers on the fatal maiden voyage of the ocean liner "Titanic", summarized according to economic status (class), sex, age and survival. A minimal reproducible example consists of the following items: a minimal dataset, necessary to reproduce the error. c++. However, there are many users that might be sceptical of pasting even a chunk of their data. Can we simplify the course notes? This action launches a CI job, which It would be nice to have a complete answer. If a courses materials fail these checks, we are notified Some classic examples: Inspect the built-in datasets to find one suitable for your problem. example.Rproj renv.lock sleep.R README.md Minimal example of reproducible analysis To run the analysis contained in sleep.R in the same environment it was created: Pull the docker image from DockerHub: docker pull csgroen/blog_example Download this repo (e.g. This means that the person reading your question can reproduce what you are seeing. To do so: This does take some work, but it seems like a fair trade-off since you ask others to do work for you. Making a vector is easy. wakefield allows the user to share minimal code to reproduce data. All techniques I explained are used in package help pages, and in tutorials and presentations I give about R. The data is sometimes the limiting factor, as the structure may be too complex to simulate. You can define your structure firstly. The main thing to do is simplify your problem as much as possible before you ask your question. What other information should you include? Minimal reproducible example for `mkdocstrings` Python handler issue Feb 14, 2022 3 min read Requirements python=^3.10 poetry Example # Install Dependencies $ poetry install # Enter Shell $ poetry shell # Serve Docs $ mkdocs serve INFO - Building documentation. Sometimes it is necessary to add some randomness to it, and there are a whole number of functions to make that. Sample size can be adjusted). Even in this silly example, I think the code is clearer than the words. Subset your data. There are four things you need to include to make your example reproducible: required packages, data, code, and a description of your R environment. All analyses described below are available as fully reproducible and executable Jupyter notebooks (available in the Data Availability section). Having a CI ensured we had an (internally) reproducible example, as plotted for each technique in Figure 1. Sometimes I even get emails with attached word documents that contain SCREENSHOTS of code. What are your tips for creating an excellent example? . raised an issue against the It will give your code nice syntax highlighting, and you dont have to worry about anything getting mangled by the email system. Notice also that the entirety of the output is in a nice single, long line, not a tall paragraph of chopped up lines. In these cases you can convert back to a regular data frame before sharing, dput(as.data.frame(my_data)). Which reserved words should one avoid, in addition to c, df, data, etc.? example with the Dockerfile: By simplifying the problem, we were now in a position to ask for help It saves package developers time in wading through messy code that is not relevant to the apparent bug. This is efficient for smaller examples rather than big ones. (Here's my advice from How to write a reproducible example. What is the meaning of to fight a Catch-22 is to accept it? Other packages might contain additional datasets. Peak Area Counts 30,000 25,000 Microlab 600 (R2 = 0.9992) 15,000 10,000 Volumetric (R2 = 0.9935) 5,000 0 Pipettes (R2 = 0.9931) 0 5 10 15 20 . There are built-in sf datasets that can be used in a reprex, but sometimes it's necessary to provide a sample of one's own data, because it's specifically, What is your frontend? For example. Basically, a minimal reproducible example (MRE) should enable others to exactly reproduce your issue on their machines. When conflicts arise with packages, giving the output of sessionInfo() can really help. The R-help mailing list has a posting guide which covers both asking and answering questions, including an example of generating data: Examples: Sometimes it helps to Python, Stan, TensorFlow, and others. To ease this burden, and to assist in ensuring You are most likely to get good help with your R problem if you provide a reproducible example. A MRE consists of the following items: a minimal dataset, necessary to demonstrate the problem; the minimal runnable code necessary to reproduce the error, which can be run on the given dataset; It's easy to provide a sample data set. Yes: a simple R A reproducible example allows someone else to recreate your problem by just copying and pasting R code. The provided reproduction is a minimal reproducible example of the bug. did you load your library in the reprex? I have a very easy and efficient way to make a R example that has not been mentioned above. Can we reproduce the issue without R Markdown? if you have over 20 lines of text + code, you can probably go back and simplify, simplify your code as much as possible while preserving the problem/error, If you have your own dataset, include them with, Try to describe the output you need as simply as possible, Do it yourself before you ask the question, It is easy to upload an image, so upload plots if you have. sample() can randomize a vector, or give a random vector with only a few values. packages has it dangers: a change to a package used by a course can Everything went dark and you cannot check the cables on the back of the computer because the lights are off due to the power outage. Running your code I think the answer is the last one. Posted on May 31, 2022 by The Jumping Rivers Blog in R bloggers | 0 Comments. The file should contain the following three sections: Packages to be loaded . For example, to recreate the mtcars dataset in R, I'd perform the following steps: Run dput (mtcars) in R Copy the output In my reproducible script, type mtcars <- then paste. Those that take the trouble to provide minimal, reproducible examples are far more likely to be answered quickly, and accurately. from others. However, all the above answers are great, and they are very important to think about and use when one wants to make a reproducible data example. As such, we ConfirmConvergence: Check R hat criterion; Confirm_hit_rates_are_correctly_made_in_case_of_MRMC: Check whether each hit-rate is defined correctly; CoronaVirus_Disease_2019: Who should be inspected? If myData is the name of your object to reproduce, run the following in R: This function is an intelligent wrapper to dput and does the following: DF is about 100 x 102. As mt1022 noted, " good package for producing minimal, reproducible example is "reprex" from tidyverse". I'm confused about the scope of the question. Over the last few years, we increased both the number and types of There are probably others. suddenly cause our teaching materials to begin failing our build checks. package. When discussing performance with colleagues, teaching, sending a bug report or searching for guidance on mailing lists and here on SO, a reproducible example is often asked and always helpful. When talking about connections to other applications (be it through ODBC or anything else), one should also provide version numbers for those, and if possible, also the necessary information on the setup. We show below how to create such CV in R with a minimal reproducible example. A minimal reproducible example After all of our simplifications, we arrived at a minimal reproducible example with the Dockerfile: FROM rocker/r-ver:latest RUN apt update && apt install -y python3 python3-dev python3-venv RUN install2.r --error reticulate COPY test.R /root/ and associated R script: What are the differences between and ? because of unloaded data or unloaded packages causes an error before that point), if you e-mail/post your code, please do so as, screenshots are awkward if we want to cut and paste code (which, again, should be, theyre also inaccessible to visually impaired people, FWIW. add which packages should be used if you use any. Thus, other people can alter your code until it runs without error. In space, no one can hear you scream. the minimal runnable code necessary to reproduce the error, which can be run on the given dataset. How do you paste data structures from r in a text format? Why is it valid to say but not ? Reducing the code to the bare minimum necessary to convey the problem makes the question easier to ask, and inherently easier to answer. This is a very basic example for using knitr in R. you will see how to produce a pdf with your code and plots in a simple way using R. use scheduled CI runs. I haven't actually seen this done, because people who can't release their data are sensitive about releasing it any form, but it would seem plausible that in some cases one could still post data if it were sufficiently anonymized/scrambled/corrupted slightly in some way. You may simply copy the output and paste it into your question. If you need some spatial object as implemented in sp, you can get some datasets via external files (like ESRI shapefile) in "spatial" packages (see the Spatial view in Task Views). Yes. Issues that come with minimal repro's are resolved much more quickly than issues where a maintainer has to reproduce themselves. Bore me. To make progress, we had to simplify the docker container. from one of the {reticulate} developers. How to create example data set from private data (replacing variable names and levels with uninformative place holders)? A MRE consists of the following our Using set.seed() you may specify a seed1, i.e. In most cases, just the R version and the operating system will suffice. Notice below how species is a factor with only one level: One other caveat for dput is that it will not work for keyed data.table objects or for grouped tbl_df (class grouped_df) from dplyr. Their response revealed that This makes it easier to read on StackOverflow questions posts and also easier to copy+paste. Something along the lines: The data structure should mimic the idea of the writer's problem and not the exact verbatim structure. numpy, can allow the two to be friends again. Is `0.0.0.0/1` a valid IP address? ourselves the following questions: After all of our simplifications, we arrived at a minimal reproducible Note: If your data frame has a factor with many levels, the dput output can be unwieldy because it will still list all the possible factor levels even if they aren't present in the subset of your data. How to stop a hexcrawl from becoming repetitive? How to add labels at the end of each line in ggplot2? While it's not absolutely sufficient to follow the check list, it provides a necessary . The anonymize function from the package SciencesPo is very silly, but for me it works nicely with the dput function. When should you include library() or require() statements? All techniques showed a high correlation but the Microlab 600 was the highest with a value of 0.9992. How do you paste data structures from r in a text format? Heres to hoping! But note that in order to make data as representative as the original (in case the OP cannot share the original data), it is good to add some information with the data example as (if we call the data mydf1), Moreover, one should know the type, length and attributes of a data which can be Data structures. Use the reprex -package to Build Your Reproducible Example When creating a reprex by hand, it's easy to accidentally miss something that means your code can't be run on someone else's computer. Yes: we were able to find a single informative, Use comments to indicate where your problem lies. Preliminary note: Sometimes you may need special formats (i.e. rev2022.11.15.43034. http://adv-r.had.co.nz/Reproducibility.html. The shorter your code is, the easier it is to understand. For most cases, this can be easily done by just providing a vector / data frame with some values. automatically runs our tests and checks against a courses training Unfortunately, the traceback given by the CI wasnt the most Personal and Private Information services. This is called creating a minimal, reproducible example ( reprex ); a minimal, complete, and verifiable example ( mcve ), or a minimal, workable example ( mwe ). Therefore, it is better to use built-in datasets or create a small "toy" example that resembles your original data, which is actually what is meant by minimal. Spend a little bit of time ensuring that your code is easy for others to read: make sure you've used spaces and your variable names are concise, but informative Someone trying to answer my question can copy/paste those two lines and start working on the problem immediately. Debian and R related packages. provide a small example that someone I'd perform the following steps: Spend a little bit of time ensuring that your code is easy for others to In these cases you can convert back to a regular data frame before sharing, dput(as.data.frame(my_data)). how-to-make-a-great-r-reproducible-example. build and test process. When should you include library() or require() statements? and. Pastebin is a website where you can store text online for a set period of time. response test run your code in a new, empty R session to make sure the code is runnable. Here are some examples of good questions: In both cases, the user's problems are almost certainly not with the simple examples they provide. To demonstrate some example use cases, we used q2-fondue and QIIME 2 to analyze publicly available marker gene, whole genome sequence and shotgun metagenome data. Code: Run-able lines of code. reproduce(
) when I need to post to StackOverflow. As a last resort, you can use dput to transform a data object to R code (e.g. In package demos? To quickly create a dput of your data you can just copy (a piece of) the data to your clipboard and run the following in R: You can change the sep in the latter if necessary. Well, not quite. Basically, a minimal reproducible example (MRE) should enable others to exactly reproduce your issue on their machines.. presents as more of a workaround than a long-term solution. Some classic examples: iris,mtcars,ggplot2::diamonds (external package, but almost everyone has it). If so, check out If your problem is specific to a type of data that is not represented in the existing data sets, then provide the R code that generates the smallest possible dataset that your problem manifests itself on. training on Docker, Make a reprex If you need help getting unstuck, the first step is to create a reprex, or reproducible example. R crashed, but the other programs are still working. What do you do in order to drag out lectures? The templated the real culprits were the incompatible BLAS (Basic Linear Algebra Filters. Not the answer you're looking for? 505), Automatically generate command to reproduce an object in the workspace, R data.frame command from existing dataframe, How to read/import a CSV once and create code so that you don't have to read/import again, How to transfer values into reproducible code, Function returning the code to create a dataframe. I routinely receive emails with code in them. use comments to indicate where your problem lies do your best to remove everything that is not related to the problem. Tho share a subset, use head (), subset () or the indices iris [1:4, ]. To solve this issue, you can use the droplevels() function. Try to locate which lines exactly result in the error. Are there other tricks in addition to using dput(), dump() or structure()? a permutation of some values : x <- sample(1:10) for vector 1:10 in random order. Pastebin.com is the number one paste tool since 2002. three systems: with all three running the same operating system, the This is merely to clarify that a reproducible example cannot and should not be the sole component of a question. an attendee would get via an install.packages() or pip install that our training materials build consistently, we developed an R Specifically, users can: generate simple ID codes (Ex001, Ex002, Ex003 ), generate hierarchical (i.e. 143 - Minimal Reproducible Example - - Genero programming: Genero is a development and deployment infrastructure designed to boost developer productivity. Personally, I prefer "one" liners. You can now specify how many lines of text output will take up (i.e., what you will paste into StackOverflow). In order to get help, it was crucial to simplify the problem. Main requirements Use the smallest, simplest, most built-in data possible. I wonder if an http://old.r-fiddle.org/ link could be a very neat way of sharing a problem. A comprehensive list of built-in datasets can be seen with data(). opted to build the numpy package from source at image build-time, getting notifications about our Introduction to Python course: Do you require help building a Shiny app? In short, whilst we had a reproducible example of the error, it was only First try to locate which lines exactly result in the error. Notice below how species is a factor with only one level, e.g. Combined with the minimal data (see above), your code should exactly reproduce the problem on another machine by simply copying and pasting it. There is a short description to every dataset and more information can be obtained for example with ?mtcars where mtcars is one of the datasets in the list. Specify which R version you used for the random process, and don't be surprised if you get slightly different results when following old questions. Win-win. For some questions, specific formats can be needed. Why did The Bahamas vote against the UN resolution for Ukraine reparations? The best option by far is to rely on built-in datasets. Around early January, we started Python code chunk that caused the issue. To produce public data from private data: Comments disabled on deleted / locked posts / reviews.

How to convert a factor to integer\numeric without loss of information? This means we must always use the latest versions of packages A useful function for this is dput(), but if you have very large data, then you might want to make a small sample dataset or only use the first 10 lines or so. Feel free to use the code and adapt it to you. You haven't really added anything of substance here.
